IB/srp: Retry stale connections
When a host just goes away (crash, power loss, etc.) without tearing down its IB connections, it can get stale connection errors when it tries to reconnect to targets upon rebooting. Retrying the connection a few times will prevent sysadmins from playing the "which disk(s) went missing?" game. This would have made things slightly quicker when tracking down some of the recent bugs, but it also helps quite a bit when you've got a large number of targets hanging off a wedged server.
